Create a concrete slab

When you create a concrete slabplate that represents a concrete structure

In Tekla Structures, a slab is created by picking three or more points.

Slab may be part of a floor, for example.

, the profile you select defines the thickness of the slab and the points you pick define the shape. The corners of the slab can be chamfered.

  1. On the Concrete tab, click Slab .
  2. Pick the corner points of the slab.
  3. Click the middle mouse button.

    Tekla Structures creates the slab, using the Concrete slab properties in the property panecontrol element in Tekla Structures user interface in the form of a side pane window

    The property pane can be used to show and modify the properties of model objects.

    The property pane can be customized by using the property pane editor.


Alternatively, you can start the command in the property pane.

  1. Ensure that you have nothing selected in the model.

  2. In the property pane, click the Object type list button and select Concrete slab from the list.

    Tekla Structures starts the command and shows the properties in the property pane.

Create a round concrete slab

  1. Create a square slab with four equal sides.
  2. Select the plate(1) part that represents a flat structure

    (1) In some contexts, for example in analysis, the term plate object may be used to refer to plates.

    (2) plate that represents a steel structure

    (2) Plate is mainly used as a connection piece or as a floor plate.

  3. Double-click a handle.

    To make it easier to select the handles of the slab corners, ensure that the Direct modificationfunction that activates the mode where the model objects can be modified by using handles

    Direct modification enables additional handles and modification options.

    switch is not active.

    The Corner chamfer properties open in the property pane.

  4. In the Type list, select Rounding .
  5. In the Radius box, enter the chamfer radius.

    The radius must be equal to half of the side of the square.

  6. Click Modify.
  7. Repeat the above steps for each corner you want to chamfer.

Alternative way of creating a round slab

  1. Create a diamond-shaped slab with four equal sides.

  2. To round the corners, use the Arc point chamfer type.

Modify concrete slab properties

  1. If the property pane is not open, double-click the slab to open the Concrete slab properties.
  2. Change the properties as needed.
  3. Click Modify.

Concrete slab properties

Use the Concrete slab properties in the property pane to view and modify the properties of a concrete slab. To open the properties, double-click the concrete slab. The file name extension of a concrete slab property fileobject type specific file that contains values of properties or settings used in the property pane or a dialog box

Property files are saved in the current model folder. The user can create and modify property files and copy them to the project or firm folders for future use.

User-defined attributes related to a specific object type are stored in a separate property file.

is *.csl.

If you have customized the property pane layout, the list of properties may be different.





User-definable name of the slab.

Tekla Structures uses part names in reports and in Document manager, and to identify parts of the same type.


Thickness of the slab.


Material of the slab.


Type of finish.

Finish is user-definable. It describes how the part surface has been treated.


Use to group slabs.

For example, you can display parts of different classes in different colors.


At depth

Position depth of the concrete slab. The position is always perpendicular to the work plane.

Cast unit

Cast unit numbering

Part prefix and start number for the part position number.

Cast unit

Indicate whether the slab is precast or cast in place.

Pour phase

Pour phase of the cast-in-place parts. Use to separate pour objects from one another.

Concrete covers for rebar sets

Coordinate system

Select whether the concrete cover thickness of the rebar sets in the part is defined in the global coordinate system, or in the part's local coordinate system.

The default global and local cover thickness values are defined in the Options dialog box.

If you select the empty option, Tekla Structures uses the global values.

Top, Bottom, Sides, Front , Back, Start, End

To override global or local default values from the Options dialog box, define the cover thickness at each required part face.



Click the User-defined attributes button to open the user-defined attributes (UDAs) of the part. UDAs provide additional information about the part.
